Thank you! Great video it helped solve my issue with emission monitors not being ready. The aftermarket fuel pump had the 5V Ref and PCM signals swapped at pigtail. After I swapped the pins on 8 pin connector I got 2.7 V where before I was getting 4.07. I wonder how many fuel pumps were delivered with that quality issue. Thanks to this video I was able to get 2002 Mustang to pass CA smog.👍🏽👍🏽

Thanks ,I hook up a scan tool and read live data on the evap it ranged from 7.2 to 7.1 on a ford f150 3.7 a 2011 model so the pressure senor is bad keeps getting P0451 .
